[Cxx-abi] Re: [cxx-abi-dev] Question about guard variable typ es

long long, regardless.

But I'm still not sure I understand your concern. When you started the
thread, you said:

But of course C99 requires that long long have at least 64 bits. Are you
concerned about the possibility that in some implementation long long might
actually have, say, 128 bits? Or that some implementation that supports a
type called long long may define it as having only 32 bits?

Personally, I think the change you suggest is editorial, for all practical
purposes. I'm just trying to understand how it might be substantive (and
therefore require any change to G++ if it isn't made).
